Traditionally, the number of citations that a scholarly paper receives from other papers is used as the proxy of its scientific impact. Yet citations can come from domains outside the scientific community, and one such example is through patented technologies—paper can be cited by patents, achieving technological impact. While the scientific impact of papers has been extensively studied, the technological aspect remains less known in the literature. Here we aim to fill this gap by presenting a comparative study on how 919 thousand biomedical papers are cited by U.S. patents and by other papers over time. We observe a positive correlation between citations from patents and from papers, but there is little overlap between the two domains in either the most cited papers, or papers with the most delayed recognition. We also find that the two types of citations exhibit distinct temporal variations, with patent citations lagging behind paper citations for a median of 6 years for the majority of papers. Our work contributes to the understanding of the technological impact of papers. 相似文献

News mentions to academic papers has provided an important channel for research to yield impact on broad audience in the society, and is particularly useful in scholarly communication, scientific outreach and altmetrics. Unlike academic paper, news articles are often influenced by social factors such as culture, ideology and geography. It is therefore uncertain whether news mentions to academic paper is valid for evaluative purpose as expected by altmetrics studies. In response, this study has conducted large scale statistical analysis to explore country's preference over news mentions, based on the assumption that if news mentions to academic paper is not (or weakly) influenced by social factors, no obvious country's preference would be observed, and the vice versa. The major findings are: (1) From the macro perspective, overall distribution of news mentions is highly imbalanced, with several developed countries taking the dominant position. However, no obvious preference towards domestic papers was observed. (2) From the micro perspective, based on the ZINB test results, news from all countries have more positively mentioned domestic papers and simultaneously shown preference over papers from certain countries. (3) In terms of disciplinary comparison, disciplinary differences were observed in the impact strength and specific preference. These results suggest that in micro level country's preference exist for news mentions to academic papers, but in macro level, country's preference is insignificant. Therefore, it is suggested that news mentions can be used for assessing purpose in the macro level. 相似文献

[目的/意义] 论文引用专利的“反向引用”也是科学与技术知识关联的重要体现。针对现有“反向引用”研究的不足,分析中国专利技术对世界科学研究的影响。[方法/过程] 搜集整理中国专利被世界科学论文引用的数据,利用文献计量学方法分析“反向引用”的引用频数、技术关联度、引用时滞及技术循环周期等指标,利用社会网络分析方法构建“反向引用”网络,探讨技术领域到科学领域的知识流动情况。[结果/结论] 中国专利技术对世界科学研究的影响力越来越大。科学与技术的双向互动在化学领域体现的最为明显,化学、工程、材料科学三个学科领域较多地吸收了专利知识,技术关联度较高。前1-4年的技术对当前科学影响最大,中国专利被科学文献引用的循环周期较短,平均为4.69年。 相似文献

This study examines independent news startups with self-reported revenue earnings in high-, middle-, and low-income categories and compares them in the areas of news content creation. The findings, based on a content analysis of 704 articles, reveal that low-revenue earners publish fewer stories than middle- and high-revenue earning sites. For-profit sites publish significantly more in low- and mid-revenue earning categories but non-profits publish significantly more in high-revenue earning sites. Most stories are still covered by editorial staff, including articles in the field of entertainment, lifestyle/health and community events about people, usually considered the domain of citizen reporters. The discussion section contextualizes these findings and recommends future research could consider examining these sites separately rather than clubbing them under the umbrella of “digital local independent startups.” 相似文献

高Altmetrics指标科技论文学术影响力研究 总被引:9,自引:0,他引:9
引入"公平性测试"方法以消除时间窗口对被引次数的影响。以高Altmetrics指标论文作为样本,选取与样本论文发表在同一期刊同一期上前后两篇论文作为参照。利用Altmetric.com、Web of Science分别获取273篇样本及参照论文的Altmetric分数、底层数据值和被引用次数。通过比较分析后发现:Altmetrics和引文数两种指标反映出读者对文献的不同关注方向,底层数据源中大众媒体对于Altmetric分数的影响最明显,高Altmetrics指标论文同时具有较高的学术影响力。作为一种早期指标,高Altmetrics指标在一定程度上能够被视作文章在未来获得高被引的风向标。 相似文献

文章以1989-2018年中国农业经济领域学者的JCR期刊论文为分析样本,从发文规模、论文影响力、研究主题、在国际化研究中的贡献度等视角,对比分析中国学者国际化论文在世界中所处的地位,全面了解中国学者在国际化研究中所发挥的角色作用。分析发现,中国学者的国际化论文在规模和影响力上有所提升,但与美国、英国等农业科技强国的差距明显;尽管涌现出多个国际化研究的中国机构,但国际合作是中国研究走向世界舞台的主要途径。不过,中国机构间初步形成国际化研究合作网络,中国学者在国际合作研究中的贡献度也有明显提升,未来需要进一步培育中国机构和学者的内生能力,为全球农业经济和政策发展贡献有影响的中国理论。 相似文献

主题科学传播在选题策略和传播渠道均存在其特点。选取我国新型冠状病毒肺炎学术成果交流平台2020年1月27日至7月19日网络载文作为典型案例,收集单篇论文的阅读量、题目、期刊、作者信息及网页访问量构成,定性分析论文学科属性与传播主题的关联,定量分析全球访问量的国别特征、构成及趋势。高阅读量论文的选题呈现以下3个特点:与中心事件强相关、与关键问题有结合点、研究对象较受关注,单篇阅读量较高的论文类型为论著、指南共识、述评专论。网络传播中以直接访问与外部链接引流为主要渠道,引流来源以自建网络平台、文献数据库、主流搜索产品(如百度学术)为主。随着疫情形势变化及观察时间窗延长,访问量增幅较大的渠道以微信公众平台及社交媒体为主,新增渠道包括不同出版平台资源中心外链及大众新闻媒介。除我国外,访问量较高的国家为美国、巴西、印度、日本、意大利。主题科学传播中传播迅速且较受关注的论文选题兼顾学科关联性及公众关切,传播渠道以网络为主。随着时间推移,即时通讯及社交媒体传播增速较高,更多境外网络访问、出版机构互链及国际学术组织数据库涉入,科学传播的受众角色更加丰富。中文论文的国际推广应注重传统平台及新兴渠道的均衡发力,凭借国际化资源中心及社交媒体平台主动传播。 相似文献

How do scientific knowledge and technological knowledge interact to influence patent inventions? This study combines the “Reliance on Science in Patenting” dataset with the PATSTAT database to investigate focal patents and their paper references and patent references. A temporal investigation shows a growing tendency that patents absorb more knowledge from patents than papers. Additionally, we conduct two sets of analyses, namely, studying the knowledge flow among 35 technology fields and 39 science fields and estimating the impact of cited references on patent impact. The results show that the fields are heterogeneous in absorbing scientific knowledge and technological knowledge. The empirical models indicate that the knowledge depth of both science and technology show an inverted U-shaped relationship with patent impact, while the curve of former is steeper. The knowledge breadth of both science and technology present a U-shaped relationship with patent impact, while the curve of latter is steeper. We also explore the impact of time lags and time spread on citations and estimate their joint effects. Our study provides a new understanding of the convergence of scientific knowledge and technological knowledge to facilitate patent inventions. 相似文献

新闻报道中的图书馆形象建构 总被引:1,自引:0,他引:1
良好的形象是图书馆的无形资产。文章通过对近三年来国内10种主流报纸中含有图书馆的新闻报道进行内容分析,研究发现报道主题主要是读者与读者服务、图书馆发展、图书馆活动、数字图书馆建设、图书馆人、社会捐赠等,但缺乏一定的深度,报道倾向以中性和正面报道为主。在此基础上提出应重视图书馆形象管理、提高与媒体对话能力、加强自身服务能力和资源建设、以组织文化塑造图书馆形象等建议。 相似文献
